MOSCOW , Russia -LRB- CNN -RRB- -- Russian space officials say the crew of the Soyuz space ship is resting after a rough ride back to Earth .

A South Korean bioengineer was one of three people on board the Soyuz capsule .

The craft carrying South Korea 's first astronaut landed in northern Kazakhstan on Saturday , 260 miles -LRB- 418 kilometers -RRB- off its mark , they said .

Mission Control spokesman Valery Lyndin said the condition of the crew -- South Korean bioengineer Yi So-yeon , American astronaut Peggy Whitson and Russian flight engineer Yuri Malenchenko -- was satisfactory , though the three had been subjected to severe G-forces during the re-entry .

Search helicopters took 25 minutes to find the capsule and determine that the crew was unharmed .

Officials said the craft followed a very steep trajectory that subjects the crew to gravitational forces of up to 10 times those on Earth .

Interfax reported that the spacecraft 's landing was rough .

This is not the first time a spacecraft veered from its planned trajectory during landing .

In October , the Soyuz capsule landed 70 kilometers from the planned area because of a damaged control cable . The capsule was carrying two Russian cosmonauts and the first Malaysian astronaut . E-mail to a friend
